Technical Information and Advantages

Due to its excellent mechanical properties, the material 1.7734 / 15CDV6 meets the requirements of international quality- and safety standards. The material is therefore suitable for the production of components intended for application ranges with maximum demands, as for instance aviation and formula 1.
The material, which is available in grain size 5 or finer (acc. EN 103-71) stands out for the following special features:
- High yield strength and excellent weldability.
- Weldable without subsequent heat-treatment, in both conditions (.4/.5)
- High resistance of the weld, without subsequent heat-treatment
(Rm > 980 N/mm2).
- The tubes are demagnetized to a residual field intensity of
12 A/cm max.
